CROSS-REFERENCE TO RELATED APPLICATION

This application is the continuation of U.S. application Ser. No. 15/258,438, filed Sep. 7, 2016, which claims the benefit of priority to Korean Patent Application No. 10-2015-0189439, filed on Dec. 30, 2015 with the Korean Intellectual Property Office, the entirety of which is incorporated herein by reference.

BACKGROUND

The present disclosure relates to a multilayer ceramic capacitor and a board having the same.

A multilayer ceramic capacitor (MLCC) has features such as a compact size, high capacitance, and ease of mountability.

The multilayer ceramic capacitor may be mounted on circuit boards of several electronic products such as display devices including liquid crystal displays (LCDs), plasma display panels (PDPs), and the like, computers, smartphones, mobile phones, and the like, to thereby serve to charge and discharge electricity.

In the multilayer ceramic capacitor as described above, a body is formed by stacking a plurality of dielectric layers and internal electrodes. The larger the numbers of stacked dielectric layers and internal electrodes in a multilayer body, the higher a probability that a step will be generated in a margin portion in which the internal electrode is not formed.

Where the step is generated as described above, when the multilayer body is compressed, both end portions of the internal electrodes in a length direction may be bent in order to fill an empty space of the multilayer body in which the step is formed.

Therefore, a thickness of both edge portions of the body in the length direction in which the end portions of the internal electrodes are positioned may become thinner than that of a central portion of the body, thereby causing defects such as short circuits and a high voltage stress (HVS) defect in the multilayer ceramic capacitor.

The HVS defect may cause a structural defect when performing a test that involves applying a voltage higher than a rated voltage in a short time period.

SUMMARY

An aspect of the present disclosure provides a multilayer ceramic capacitor capable of decreasing a step generated when a multilayer body is compressed, and a board having the same.

The multilayer ceramic capacitor may include a capacitor body formed by stacking a plurality of dielectric layers and a plurality of first and second internal electrodes in a width direction, the first and second internal electrodes including body portions overlapping each other and one or more lead portions exposed to a mounting surface of the capacitor body and disposed to be spaced apart from each other, respectively; and first to third external electrodes disposed on the mounting surface of the capacitor body to be connected to respective lead portions wherein the body portions of the first and second internal electrodes are formed to have different areas from each other.

DETAILED DESCRIPTION

Hereinafter, embodiments of the present disclosure will be described as follows with reference to the attached drawings.

The present disclosure may, however, be exemplified in many different forms and should not be construed as being limited to the specific embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Throughout the specification, it will be understood that when an element, such as a layer, region or wafer (substrate), is referred to as being “on,” “connected to,” or “coupled to” another element, it can be directly “on,” “connected to,” or “coupled to” the other element or other elements intervening therebetween may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another element, there may be no other elements or layers intervening therebetween. Like numerals refer to like elements throughout. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

It will be apparent that though the terms first, second, third, etc. may be used herein to describe various members, components, regions, layers, and/or sections, these members, components, regions, layers, and/or sections should not be limited by these terms. These terms are only used to distinguish one member, component, region, layer, or section from another region, layer, or section. Thus, a first member, component, region, layer, or section discussed below could be termed a second member, component, region, layer, or section without departing from the teachings of the exemplary embodiments.

Spatially relative terms, such as “above,” “upper,” “below,” and “lower” and the like, may be used herein for ease of description to describe one element's relationship relative to another element(s) as shown in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “above” other elements, or “upper,” would then be oriented “below” the other elements or features, or “lower.” Thus, the term “above” can encompass both the above and below orientations depending on a particular direction of the figures. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein may be interpreted accordingly.

The terminology used herein describes particular embodiments only, and the present disclosure is not limited thereby.

Hereinafter, embodiments of the present disclosure will be described with reference to schematic views illustrating embodiments of the present disclosure. In the drawings, for example, due to manufacturing techniques and/or tolerances, modifications of the shape shown may be estimated. Thus, embodiments of the present disclosure should not be construed as being limited to the particular shapes of regions shown herein, for example, to include a change in shape results in manufacturing. The following embodiments may also be constituted by one or a combination thereof.

The contents of the present disclosure described below may have a variety of configurations and propose only a required configuration herein, but are not limited thereto.

Directions of a hexahedron will be defined in order to clearly describe exemplary embodiments in the present disclosure. L, W, and T shown in the accompanying drawings refer to a length direction, a width direction, and a thickness direction, respectively.

Here, the width direction may be the same as a stacking direction in which dielectric layers are stacked.

Multilayer Ceramic Capacitor

FIG. 1 is a perspective view schematically illustrating a multilayer ceramic capacitor according to an exemplary embodiment in the present disclosure, FIG. 2 is a perspective view illustrating a body of the multilayer ceramic capacitor shown in FIG. 1 so that amounting surface thereof is directed upward, FIG. 3 is a separate perspective view illustrating a stacking structure of first and second internal electrodes of the multilayer ceramic capacitor shown in FIG. 1, and FIG. 4 is a cross-sectional view taken along line I-I′ of FIG. 1.

Referring to FIGS. 1 through 4, a multilayer ceramic capacitor 100 according to the present exemplary embodiment may include a body 110 and first to third external electrodes 131 to 133.

The body 110 may include a plurality of dielectric layers 111 stacked in the width direction and a plurality of first and second internal electrodes 121 and 122 alternately disposed in the width direction with dielectric layers 111 interposed therebetween.

The body 110 may be formed by stacking the plurality of dielectric layers 111 and the first and second internal electrodes 121 and 122 in the width direction and sintering the stacked dielectric layers and internal electrodes, and a shape of the body 110 is not particularly limited, but may have a substantially hexahedral shape as illustrated.

In this case, the body 110 may have first and second surfaces S1 and S2 opposing each other in the thickness (T) direction, third and fourth surfaces S3 and S4 connecting the first and second surfaces S1 and S2 to each other and opposing each other in the length (L) direction, and fifth and sixth surfaces S5 and S6 opposing each other in the width (W) direction.

Hereinafter, in the present exemplary embodiment, a description will be provided with a mounting surface of the multilayer ceramic capacitor 100 being the first surface S1 of the body 110.

The dielectric layers 111 may be in a sintered state, and adjacent dielectric layers 111 may be integrated with each other so that boundaries therebetween are not readily apparent without a scanning electron microscope (SEM).

In this case, a thickness of the dielectric layer 111 may be suitably changed according to a capacitance design of the multilayer ceramic capacitor 100. Further, the dielectric layer 111 may contain ceramic powder having high permittivity, such as a barium titanate (BaTiO₃) based powder, a strontium titanate (SrTiO₃) based powder, magnesium titanate, or the like, but the material of the dielectric layer 111 is not limited thereto as long as sufficient capacitance may be obtained.

In addition, if necessary, at least one of a ceramic additive, an organic solvent, a plasticizer, a binder, a dispersant, and the like, may be further added to the dielectric layer 111 together with the ceramic powder.

Further, covers 112 and 113 may be respectively disposed on the outermost portions of the body 110 in the width direction as margins.

The covers 112 and 113 may have the same material and configuration as those of the dielectric layer 111 except that internal electrodes are not included therein.

The covers 112 and 113 may be formed by stacking one or two or more dielectric layers on the outermost portions of the body 110 in the width direction, respectively, and may generally serve to prevent the first and second internal electrodes 121 and 122 from being damaged by physical or chemical stress.

The first and second internal electrodes 121 and 122, which are electrodes applied with different polarities, may be alternately disposed in the body 110 with dielectric layers 111 interposed therebetween in the width direction.

The first and second internal electrodes 121 and 122 may be electrically insulated from each other by the dielectric layers 111 interposed therebetween.

A material forming the first and second internal electrodes 121 and 122 is not particularly limited. For example, the first and second internal electrodes 121 and 122 may be formed using a conductive paste formed of at least one among a noble metal material such as palladium (Pd), a palladium-silver (Pd—Ag) alloy, or the like, nickel (Ni), and copper (Cu).

A printing method for the conductive paste may be a screen printing method, a gravure printing method, or the like, but the present disclosure is not limited thereto.

The first and second internal electrodes 121 and 122 according to the present exemplary embodiment may be disposed to be spaced apart from the third and fourth surfaces S3 and S4 of the body 110 by a predetermined distance, and margins in the length direction may be formed in the body 110 in accordance with a spaced distance.

The first internal electrode 121 may include a first body portion 121 a overlapping a second body portion 122 a of the second internal electrode 122 disposed adjacent thereto in the width direction to contribute to forming capacitance, and first and second lead portions 121 b and 121 c extended from the first body portion 121 a to thereby be exposed to the first surface S1 of the body 110.

The first and second lead portions 121 b and 121 c may be disposed to be spaced apart from each other in the length direction of the body 110 and contact the first and third external electrodes 131 and 133 to thereby be electrically connected thereto, respectively.

The second internal electrode 122 may include a second body portion 122 a overlapping the first body portion 121 a of the first internal electrode 121 disposed adjacent thereto in the width direction to contribute to forming capacitance, and a third lead portion 122 b extended from the second body portion 122 b to thereby be exposed to the first surface S1 of the body 110.

The third lead portion 122 b may be disposed between the first and second lead portions 121 b and 121 c in the length direction of the body 110 and may contact the second external electrode 132 to thereby be electrically connected thereto.

Since the first and second lead portions 121 b and 121 c of the first internal electrode 121 and the third lead portion 122 b of the second internal electrode are disposed on the first surface S1 of the body 110 to be maximally adjacent to each other, the multilayer ceramic capacitor 100 according to the present exemplary embodiment may have low ESL.

An area of the second body portion 122 a may be different from that of the first body portion 121 a. While the second body portion 122 a is illustrated with a larger area than the first body portion 121 a, the present disclosure is not limited thereto and the first body portion 121 a may have an area larger than that of the second body portion 122 a.

In the present exemplary embodiment, the second body portion 122 a may have an area larger than that of the first body portion 121 a by forming the second body portion 122 a to have a length longer than that of the first body portion 121 a and a height greater than that of the first body portion 121 a.

Where the areas of the first and second body portions 121 a and 122 a are different from each other, the position of the step may be changed from an upper portion of the body 110 to a lower portion thereof. In general, when a high voltage is applied to a multilayer ceramic capacitor, a defect such as an HVS defect may occur in end portions of internal electrodes in which a step is generated. When the position of the step is changed from the upper portion of the body to the lower portion, the HVS defect may be decreased.

According to the present exemplary embodiment, a current may flow from the first and third external electrodes 131 and 133 to the second external electrode 132. Since area distribution of a current loop, which is the shortest distance on the internal electrodes in which the current of the multilayer ceramic capacitor flows, is decreased by the structure as described above, ESL may be additionally further decreased as compared to a structure in which areas of first and second body portions are the same.

The first and second body portions 121 a and 122 a are not limited to that embodiment, and as illustrated in FIG. 5, the second body portion 122 a′ may have the same length as that of the first body portion 121 a and have a height greater than that of the first body portion 121 a.

In this case, the second body portion 122 a′ may be expanded so that its height in a direction away from the mounting surface is the same as that of the first body portion 121 a, but its height in a direction toward the mounting surface of the body 110 is larger than the first body portion 121 a.

The structure as described above results in a smaller decrease to the an HVS defect rate, but permits an increased margin of the dielectric layer 11 in the length direction and an increased upper margin in the thickness direction, which may advantageously decrease a cutting defect rate and improve reliability.

FIG. 7 is a graph illustrating an HVS defect rate depending on a difference in size between internal electrodes of a multilayer ceramic capacitor according to the present disclosure, and FIG. 8 is a graph illustrating equivalent series inductance (ESL) depending on the difference in size between internal electrodes of the multilayer ceramic capacitor according to the present disclosure.

The following Table 1 illustrates the results of FIG. 7 in more detail. Hereinafter, the HVS defect rate, a cutting defect rate, and a change in ESL depending on the difference in size between the internal electrodes according to the present disclosure will be described with reference to Table 1 and FIGS. 7 and 8.

TABLE 1 Difference in Each Length and Width between First and HVS Cutting Second Internal Electrodes Defect Rate Defect Rate No. (μm) (%) (%) 1 0 41 5.1 2 5 38 5.2 3 10 29 6.4 4 15 24 7.2 5 20 21 8.5 6 25 18 11.4 7 30 17 25.8 8 35 15 27.8 9 40 15 32.5 10 45 14 48.5 11 50 16 55.2

In this case, the size of the multilayer ceramic capacitor was 2.0×1.2×1.0 mm (length×width×thickness), the thickness of the first and second internal electrodes was 0.5 μm, the thickness of the dielectric layers was 0.9 μm, and the number of stacked first and second internal electrodes was 800. The difference in each width and length between the first and second internal electrodes was limited to 50 μm, at which point the HVS defect rate was saturated.

Referring to Table 1 and FIG. 7, in sample 1, in which there was no difference in each length and width between the first and second internal electrodes, the HVS defect rate was more than 40%. As shown in Table 1 and FIG. 7, as the difference in each length and width between the first and second internal electrodes was increased by 5 μm, the HVS defect rate was gradually decreased.

In sample 11, in which the difference in each length and width between the first and second internal electrodes was 50 μm or more, the cutting defect rate was more than 50%, the basis for determining a good product. Therefore, it may be preferable that the difference in each length and width between the first and second internal electrodes is less than 50 μm. In addition, more preferably, the difference in each length and width between the first and second internal electrodes may be in a range of 25 μm or less in which the cutting defect rate was not over 20% (samples 1 to 6).

In general, when first and second internal electrodes are stacked in a multilayer ceramic capacitor in a zigzag form, an increase and distribution of current loop may be generated.

Referring to FIG. 8, as the difference in area between the first and second body portions was increased, an ESL value was decreased, and distribution of ESL (a length of a vertical line) was also decreased. Here, a middle horizontal line of a bar graph indicates an average value.

Referring to FIG. 4, the first to third external electrodes 131 to 133 may be sequentially disposed on the first surface S1 of the body 110 to be spaced apart from each other in the length direction of the body 110.

Further, the first to third external electrodes 131 to 133 may be disposed to be spaced apart from the third and fourth surfaces S3 and S4 of the body 110.

The first to third external electrodes 131 to 133 may respectively include conductive layers 131 a to 133 a formed on the first surface S1 of the body 110, and plating layers respectively formed on the conductive layers 131 a to 133 a, wherein the plating layers may include nickel (Ni) plating layers 131 b to 133 b and tin (Sn) plating layers 131 c to 133 c respectively formed on the nickel (Ni) plating layers 131 b to 133 b.

Since, in a general multilayer ceramic capacitor, external electrodes are disposed on both ends of a body opposing each other in a length direction of the body, when applying an alternating current to the external electrodes, a current path is long, and thus a current loop is large, which may increase the size of the induced electric field, thereby causing an increase in inductance of an electronic component.

In the present exemplary embodiment, since the first to third external electrodes 131 to 133 are disposed on the first surface S1 of the body 110, a current path may be shortened, and thus, the current loop may be decreased, thereby decreasing inductance of an electronic component.

As illustrated in FIG. 6, first to third external electrodes 131′ to 133′ of a multilayer ceramic capacitor 100′ may respectively include connection portions 131 a to 133 a formed on a first surface S1 of a body 110, and first to third band portions 131 b to 133 b extended from the connection portions 131 a to 133 a to portions of fifth and sixth surfaces S5 and S6 of the body 110, thereby improving adhesion strength of the first to third external electrodes 131′ to 133′.

Modified Exemplary Embodiment

FIG. 9 is a perspective view illustrating a multilayer ceramic capacitor according to another exemplary embodiment in the present disclosure, FIG. 10 is a separate perspective view illustrating a stacking structure of first and second internal electrodes of FIG. 9, and FIG. 11 is a cross-sectional view taken along line II-II′ of FIG. 9.

A description of the same portions as those in the exemplary embodiment described above will be omitted in order to prevent an overlapping description, but first and second internal electrodes and fourth to sixth external electrodes having different structures from those in the exemplary embodiment described above will be described in detail.

Referring to FIGS. 9 through 11, a multilayer ceramic capacitor 100″ according to the present exemplary embodiment may include fourth to sixth external electrodes disposed on a second surface S2 of a body 110.

The fourth to sixth external electrodes 134 to 136 may be sequentially disposed to be spaced apart from each other in a length direction of the body 110.

The fourth to sixth external electrodes 134 to 136 may be disposed to be spaced apart from third and fourth surfaces S3 and S4 of the body 110.

Further, the fourth to sixth external electrodes 134 to 136 may respectively include conductive layers formed on the second surface S2 of the body 110 and plating layers formed on the conductive layers.

The plating layers may include nickel (Ni) plating layers and tin (Sn) plating layers formed on the nickel (Ni) plating layers.

The first internal electrode 121 may include fourth and fifth lead portions 121 d and 121 e extended from the first body portion 121 a to thereby be exposed to the second surface S2 of the body 110, respectively.

The fourth and fifth lead portions 121 d and 121 e may be disposed to be spaced apart from each other in the length direction of the body 110 and contact the fourth and sixth external electrodes 134 and 136 to thereby be electrically connected thereto, respectively.

The second internal electrode 122 may include a sixth lead portion 122 c extended from a second body portion 122 a to thereby be exposed to the second surface S2 of the body 110.

The sixth lead portion 122 c may be disposed between the fourth and fifth lead portions 121 d and 121 e in the length direction of the body 110 and may contact the fifth external electrode 135 to thereby be electrically connected thereto.

When the internal and external electrodes of the multilayer ceramic capacitor 100″ are formed to have vertically symmetrical structures as described above, directionality of the capacitor may be removed.

Therefore, since any surface of the first and second surfaces S1 and S2 of the multilayer ceramic capacitor 100′ may be provided as a mounting surface, at the time of mounting the multilayer ceramic capacitor 100″ on a circuit board, there is no need to consider a direction of the mounting surface.

Referring to FIG. 12, fourth to sixth external electrodes 134′ to 136′ of a multilayer ceramic capacitor 100′″ may include connection portions 134 a to 136 a formed on a second surface S2 of a body 110, and fourth to sixth band portions 134 b to 136 b extended from the connection portions 134 a to 136 a to portions of fifth and sixth surfaces S5 and S6 of the body 110, respectively. Therefore, adhesion strength of the fourth to sixth external electrodes 134′ to 136′ may be improved.

FIG. 13 is a perspective view illustrating the multilayer ceramic capacitor of FIG. 1 mounted on a circuit board.

Referring to FIG. 13, a board 200 having a multilayer ceramic capacitor 100 according to the present exemplary embodiment may include a circuit board 210 on which the multilayer ceramic capacitor 100 is mounted, and first to third electrode pads 221 to 223 formed on the circuit board 210 to be spaced apart from each other.

The multilayer ceramic capacitor 100 may be electrically connected to the circuit board 210 by solder 230 in a state in which first to third external electrodes 131 to 133 are positioned to contact the first to third electrode pads 221 to 223, respectively.

Although the board in which the multilayer ceramic capacitor of FIG. 1 is mounted on the circuit board is illustrated in the present exemplary embodiment, the board is not limited thereto.

As an example, a board having a multilayer ceramic capacitor may be configured by mounting the multilayer ceramic capacitor illustrated in FIG. 9, or the like, on a circuit board in a similar structure, as illustrated in FIG. 14.

As set forth above, according to exemplary embodiments in the present disclosure, the position in which the step is generated may be alternately changed from the upper portion of the body to the lower portion thereof by allowing the body portions of the internal electrodes to have different areas from each other, whereby the high voltage stress (HVS) defect in the end portions of the internal electrodes may be decreased.
